VAPOR-BURN ER.

SPECIFICATION forming part of Letters Patent No. 401,383, dated April 16, 1889.

Application filed May 16, 1887. Serial No. 238,348. (No model.)

To all whom it may concern.-

Be it known that 1, CHARLES H. SHULTZ, a citizen of the United States, residing at St. Joseph, in the county of Buchanan and State of Missouri, have invented a new and useful Improvement in Vapor-Burners, of which the following is a specification.

My invention relates to an improvement in vapor-burners; and it consists in the peculiar construction and combination of devices, as will be more fully set forth herein after, and particularly pointed out in the claim.

In the drawings, Figure 1 is a vertical central sectional view of a vapor'burner embodying my improvement. Fig. 2 is a horizontal sectional view of the same, taken on the line a: m of Fig. 1.

A represents a cylindrical burner head, which has its lower side projected beyond the vertical side walls, B, to form a laterally outwardly-extending portion or offset, C. The said portion or oitset is hollow as shown in Fig. 1, and communicates with the interior of the burner. The under side of the outer edge of the portion or offset is rounded, as at D. This rounding of the offset is to enable the flame-jets to more readily escape over the offset and strike the sides of the vaporizingchamber.

E represents upwardly-inclined inwardlyprojecting apertures which are made in the upper side of the portion or offset 0, and F represents downwardly and outwardly inclined openings which are made through the lower side of the portion or offset 0. Formed integrally with the burner and arranged concentrically on the same is an annular vaporizing-chamber G.

It will be observed by reference to Fig. 1 that the openings E are arranged at such an angle as to project the jets of flame against the outer side of the chamber G, and thereby heat the latter so intensely as to cause the oil which is fed thereto by the usual standpipe, H, to be instantly vaporized on coming in contact with the sides of the chamber. The openings F on the lower side of the offset or portion 0 direct jets of flame downward and outward from the burner. The curved lower side, D, of the said portion or offset causes the jets projected from the openings F to curve upward around the said offset or portion.

I represents the vapor-pipe, which extends from the chamber G and terminates in avertical sleeve, K, below the center of the burner. In this sleeve is located the needle-valve L.

The lower end of the vertical sleeve K is provided with screw threads, as shown at Fig. 1.

P represents a packing-gland, which is cylindrical in shape and is provided with interior screw-threads adapted to fit the threads on the lower end of the sleeve T, and has a threaded central opening in which works the threaded portion of the valve. Packing material, R, is arranged in the packing-gland be low the sleeve and around the lower end of the needle-valve. By turning the gland so as to cause it to be screwed upward on the sleeve K the packing material may be compressed to such a degree as to absolutely prevent the escape of vapor from the lower end of the sleeve.

M represents a vertical tube, which has its upper end screwed in a central opening in the bottom of the burner. The lower end of this tube M extends through a central opening in an oil-cup, N, and serves to support the latter. 0 represents a set-screw which connects the lower end of the tube to the oil-cup.

The operation of my invention will be very readily understood.

A small quantity of oil, previously placed in the cup N, is first ignited to heat the burner and the chamber G, and a supply of oil is fed to the chamber G by the stand-pipe. As the oil reaches the chamber, it is vaporized by the heat and is fed through the pipe I and the sleeve K, and directed upward from the latter through the tube M into the burner. As the vapor passes through the tube, air is sucked in with it and becomes commingled with the vapor in the burner, thereby rendering the same combustible by oxygenizing it. As the oxygenized vapor escapes through the openings E and F, it is burned, as previously described. Particular stress is laid on the construction of the burner with the lateral offset or portion 0, the top of which is perforated to provide the jet-openings; also, the openings F in the bottom of the burner are an important feature.

It will be understood that the packing in the gland is interposed between the tube K and the threads on the valve. Heretofore, so far as I am aware, the screw-threads on the valve have extended up past the packing. This is objectionable because the residuum in the vapor Will settle on the threads and gum the latter to such an extent as to impede the Working of the valve.

By my improvement the packing effectually prevents the vapor from settling on the threads of the valve.

Having thus described my. invention, I claim- The burner A, having the annular vapormy own I have hereto affixed my signature in 30 presence oftwo witnesses. v
